太陽能發電 Solar power generation
光伏逆變器重點關注以下技術指標：
高效率：光伏逆變器的轉換效率的高低直接影響到太陽能發電系統在壽命周期內發電量的多少。根據產品型號的不同，國際一流品牌的產品的轉換效率最高可達98%以上。
長壽命：光伏發電系統設計使用壽命一般為20 年左右，所以要求光伏逆變器的設計壽命需要達到較高水平。
高可靠性：光伏逆變器發生故障將會導致光伏系統停機，直接帶來發電量的損失，所以高可靠性是光伏逆變器的重要技術指標。寬直流電壓工作范圍：因為單塊太陽電池組件的輸出直流電壓比較低，所以在實際應用中需要進行多塊串聯，得到一個較高的直流電壓，再進行多組并聯后輸入光伏逆變器。由于不同功率、不同電壓的光伏電池、不同的串并聯方案組合，要求同一規格的光伏逆變器能夠適應不同的直流電壓輸入。所以，光伏逆變器具有越寬的直流電壓工作范圍，就越能適應客戶的實際應用需求。
The following technical specifications are key considerations for photovoltaic inverters: High efficiency: The conversion efficiency of a photovoltaic inverter directly affects the amount of electricity generated by a solar power system over its lifecycle. Depending on the model, products from leading international brands can achieve conversion efficiencies of up to 98% or higher. Long service life: As the design service life of a photovoltaic power system is generally around 20 years, photovoltaic inverters must be designed to meet high standards of durability. High reliability: A fault in a PV inverter will cause the PV system to shut down, resulting in a direct loss of power generation; therefore, high reliability is a crucial technical parameter for PV inverters. Wide DC voltage operating range: As the output DC voltage of a single solar cell module is relatively low, multiple modules must be connected in series in practical applications to achieve a higher DC voltage, which is then fed into the PV inverter after being connected in parallel. Given the variety of photovoltaic cells with different power ratings and voltages, as well as the different combinations of series and parallel configurations, PV inverters of the same specification must be capable of accommodating different DC input voltages. Consequently, the wider the DC operating voltage range of a PV inverter, the better it can meet the practical application requirements of customers.
